            EXAMPLES OF SOIL RESISTIVITY
The electrical resistivity of various soil types under different climatic conditions and in the presence of underground waters.
  • Soil Types (Column 1): Lists different geological formations like clays, limestones, sandstones, quartzites, slates, granite, and fossil slates/schists/igneous rocks.

  • Normal and High Rainfall Conditions (Columns 2 & 3): Shows the probable resistivity value and the range of values encountered for each soil type in areas with greater than 500 mm of rainfall per year.

  • Low Rainfall and Desert Conditions (Column 4): Presents the range of resistivity values encountered in areas with less than 250 mm of rainfall per year.

  • Underground Waters (Salids) (Column 5): Indicates the range of resistivity values when underground waters are present.
  • Note: An asterisk indicates that the resistivity of alluvium and lighter clays under normal/high rainfall depends on the water level of the locality.
